SUBTTL Historical notes
COMMENT |
The DECnet modules were originally written and tested on a
user-mode test-bed on TOPS10. The modules at that time were
named according to current architecture names, and TOPS10
naming conventions. After getting the DECnet code running in
the TOPS10 monitor, the DECnet modules were integrated into
TOPS20 (for Release 6.1). The naming conventions used earlier
were no longer valid because the architecture group renamed
several of the DECnet layers. To resolve these problems, the
DECnet modules were renamed to names which avoided the names
the architecture group didn't want us using any more. The
result of all this is that several modules have comments and
labels which do not correspond with the current module name,
so we supply a mapping table between old names and new names
to attempt to relieve the confusion:
Old name(layer) New name New layer name
D36UNV(Universal) D36PAR (Universal file)
D36COM(Common subrs) D36COM (Common subroutines)
NSPSER(Network service) LLINKS End Communication Layer
XPTSER(Transport) ROUTER Routing Layer
SCTPRM(Session Control) SCPAR Session control parameters
SCTCON(Session Control) SCLINK Session Control Layer
SCTUUO(Session Control) SCMUUO Session control uuos
NMXCON(Network Mngmnt.) NTMAN Network Management Layer
In addition, on the -20, we needed an entirely new module for
the UUO/JSYS level code which was entirely different between
the -10 and the -20. This module was given the name SCJSYS,
and is morally equivalent to SCMUUO.

SUBTTL FIXADJ Macro - Compensate for bug in negative ADJBP
;This macro should be removed if and when the KL microcode is fixed to
;handle byte pointers that have a 777777 in the right half and an index
;AC that points to the first address in a section. Such a byte pointer
;might be generated by backing up a byte pointer with an ADJBP instruction.
;For example, if the byte pointer is 41006,,777777 and AC 6 contains 10,,0
;the effective address calculation computes an address of 7,777777. If it
;is the case that section 7 is not mapped a page fault will result even if
;the instruction is an ILDB wishing to get its byte from 10,,0. This macro
;will change the byte pointer from 410xx,,-1 to 4410xx,,0.
DEFINE FIXADJ (ac),<
TLNE ac,700000 ;Is it 0410xx,,xxx?
IFSKP.
TLO ac,400000 ;Yes, make it 4410xx,,xxx
